摘要:
A carbon fiber bundle for resin reinforcement, wherein there are adhered by 0.1-5.0 mass% to a carbon fiber bundle in which multiple lengths of filament are bundled, a mixture created by mixing an organic polymer (A) having a mass-average molecular weight of 10000 or more and an organic compound (B) the thermal reduction rate specified in claim 1 of which is 5 mass% or more or an organic compound (B) the thermal reduction rate specified in claim 2 of which is 0.8 mass% or more, the amount of the organic polymer (A) adhered being 0.1 mass% or more.

Provided are a carbon fibre thermoplastic resin prepreg which is a carbon fibre prepreg obtained by impregnating a PAN-based carbon fibre in which the average fibre fineness of a single fibre is 1.0 dtex to 2.4 dtex with a thermoplastic resin, wherein the thermoplastic resin satisfies 20 ≤ (FM/FS) ≤ 40 (where FM: flexural modulus (MPa) of a resin sheet comprising only the thermoplastic resin, and FS: flexural strength (MPa) of the resin sheet), a method for manufacturing the same, and a carbon fibre composite material employing the carbon fibre prepreg.
摘要:
A fiber-reinforced thermoplastic resin prepreg that is a fiber-reinforced polyamide prepreg which contains (A) reinforcing fibers, (B) a sizing agent and (C) a polyamide resin, and wherein the sizing agent (B) and the polyamide resin (C) satisfy the following condition. N m /N 0 m is the average of torques necessary for maintaining the number of revolutions of a roller type blade at 100 rpm/15 minutes, said average representing the fluidity of a mixture, which is obtained by mixing the sizing agent (B) and the polyamide resin (C) at 3:100 (mass ratio), in cases where the mixture is filled into a mixer having the roller type blade and heated and melted at a temperature that is higher than the melting point of the polyamide resin (C) by 30°C.)
